VS2005 compile error "C2039"

I'm upgrading a VS2003 project to VS2005 but got bunch of C2039 errors in xutility.h file during compiling:
:\Program Files\Microsoft Visual Studio 8\VC\include\xutility(610) : error C2039: 'iterator_category' : is not a member of 'ObjectBaseIteratorCL'

Any ideas? Thanks
